Pen & Paper · A photographer’s locked archive
A photographer is killed before handing over an original negative. The print left in view seems to support a different story. Find which object was substituted, who returned to the archive and whether a reporter’s payment proves involvement.
Read the case file below, or open the interactive desk to examine records, keep notes and submit your reasoning. These are the case materials, without the solution.
Alma is killed at 16:04–16:12 in room twelve. The front lobby is recorded, while a rear archive camera keeps an independent image of its latch. The retained contact sheet was sealed before the incident.
Alma’s assistant
I streamed a print demonstration from the upstairs studio.
I had used Alma’s name on my own small sale. I wanted that kept private.
The drying-line print has an image border wider than its supposed negative sleeve.
Courier
I collected an opaque print parcel at 15:45 and left by the lobby camera.
I was paid for a normal delivery.
The collection label names Jo’s newspaper, but it says nothing about the contents.
Gallery owner
I was on my shop’s continuous sales camera.
Alma planned to cancel our exhibition, which would cost me money.
Theo alone had borrowed the archive sleeve cutter that morning.
Investigative reporter
I waited outside Alma’s building. I entered only after the emergency call.
I promised to publish her evidence and paid for first access.
Alma gave me a sealed contact sheet earlier; I did not see the original negative.
Photographic restorer
I left the darkroom before 16:00 and did not return.
Photographer Alma had found evidence that my published restorations erased provenance marks.
The negative she intended to show was not the print on her drying line.
Building caretaker
I worked in the front lobby with a contractor.
Alma complained that I had lent keys to visitors. I feared dismissal.
Room twelve’s rear door uses a separate archive latch, not the front-door master key.
Read each record on its own terms. A claim made by a person is different from a fact established by an independent record.
Physical record · Gallery
Alma’s comparisons show Theo removing archive marks while claiming unaltered restorations. Her dated plan was to release the original negative as evidence.
Physical record · Archive latch
Theo’s face is clear as he enters the archive at 16:05 and leaves at 16:11 with a flat sleeve. Nobody else uses the rear door in that interval.
Physical record · Archive latch
The rear key is checked out to Theo. Bram’s front master key cannot open it. The front lobby recording shows no other entrant during the fatal interval.
Physical record · Room twelve
A deliberate close-range assault occurs at 16:04–16:12. The drying-line print is undamaged, but the original negative’s sleeve is empty.
Physical record · Room twelve
Jo’s sealed sheet records the original negative’s edge notch and an unretouched archive mark. The drying-line print crops out that edge. It cannot authenticate the original’s current presence.
Physical record · Upstairs studio
Nia remains on the gallery sales camera, Esme on her studio stream, Bram with the lobby contractor, Jo outside until the call, and Rafi on his completed delivery route.
Physical record · Upstairs studio
The stream predates the emergency and preserves Esme’s warning that the print border is wrong. Her observation directs comparison; it is not a claim that she saw the assault.
Physical record · Gallery
The empty sleeve’s distinctive cut matches the test strip made when Theo borrowed the cutter. This links the substituted packaging to his workshop; it does not alone establish the assault.
Physical record · Room twelve
Jo pays for publication rights and receives only the sealed contact sheet. The signed agreement requires preservation of the original, not its removal or Alma’s silence.
Physical record · Gallery
The original negative with the matching notch is found in Theo’s locked bench drawer. A continuous police-sealed search records the recovery.
